In an alternator, using short-pitched coils primarily helps to:

AIncrease leakage reactance
BIncrease total generated voltage
CReduce mechanical friction
DEliminate specific high-frequency harmonics from induced voltage

Explanation

Short-pitching reduces or eliminates unwanted harmonic components (like 3rd or 5th harmonics) in the generated EMF waveform, improving wave shape.
